Java Script shows up when trying to share on Facebook

We are using Rafflecopter to run contests on our site. I use Rafflecopter java script on my post page (see page: http://www.paidinstyle.com/blog/quilted-sock-monkey-wall-hanging/)
When I am trying to share a contest through Facebook share button the chunck of java script code pulled from Rafflecopter shows up which scares people to share the info.
How can I eliminate this code from sharing?
